好吧,这比我想象的要容易。就我而言,当我触摸一行时,我希望选择器显示并tableView
改变它的高度,所以我使用:
[UIView animateWithDuration:0.4 delay:0.0 options: UIViewAnimationCurveEaseOut animations:^{
self.pickerView.frame = CGRectMake(0, self.view.bounds.size.height-200, self.view.bounds.size.width, self.pickerView.frame.size.height);
// shrink the table vertical size to make room for the date picker
CGRect newFrame = self.tableView.frame;
newFrame.size.height -= self.pickerView.frame.size.height;
self.tableView.frame = newFrame;
} completion:nil];
然后,当我单击完成按钮并想要返回tableView
到全高并隐藏我的 datePicker 时,我使用:
- (void)doneWithPicker:(BOOL)remove {
CGRect newFrame = self.tableView.frame;
newFrame.size.height += self.pickerView.frame.size.height;
self.tableView.frame = newFrame;
[UIView animateWithDuration:0.4 delay:0.0 options: UIViewAnimationCurveEaseOut animations:^{
self.pickerView.frame = CGRectMake(0, self.view.bounds.size.height+300, self.view.bounds.size.width, self.pickerView.frame.size.height);
} completion:^(BOOL finished){
if (remove) {
[self.pickerView removeFromSuperview];
self.pickerView = nil;
}
}];
}
此外,当添加pickerView
作为子视图时,请确保将其添加到window
:
[self.view.window addSubview:self.pickerView];
